It's a difficult question... it seems rather niche equipment, and quite mysterious machine. Searching in the net, I couldn't even find info on Soviet machines, nor photos. There is only mention on one page, that some tanks were fitted with bulldozer equipment BTU or snow ploughs STU (https://www.aviarmor.net/tww2/tanks/ussr/t-34-85_3.htm). As for Polish ones, J. Magnuski only mentions, that in the USSR there was developed a standard tank dozer variant "ST-34", and they were used in Poland (the question is, if he doesn't confuse a designation of snow plough...). Also, no photos...

On this page http://fb2.booksgid.com/content/D4/-...008-10/29.html (article from TiV magazine on T-54 variants) there is an information, that a snow-plough STU was used also on T-34. The BTU dozer is described in T-54 context, but unfortunately without information, on which tanks it was used. It was replaced with lighter BTU-55 on T-54 and 55.
